MS-09 Dom (MS-09 ドム) is a heavy armored Mobile Suit built to surpass the Zaku and Gouf. Seeking to be Zeon's answer as their new weapon for terrestrial combat, the Dom has thrusters installed within its "skirt armor" and legs. The design specs for these thrusters are akin to those powering a jet engine, allowing the Dom to glide across surfaces at high speeds. Learning from the mistakes of their previous models, the Dom's framing has been altered to be aerodynamic and possesses an easier control scheme. The success of their testing lead to its quick mass-produced status and became Zeon's weapon of choice at Odessa and their bases throughout Asia. Its space counterpart for the same right is the Rick Dom.

The Black Tri-Stars were given the three early prototypes of the Dom, models 1~3. As an ode to their nickname, these Doms were colored under their personal colors of violet and black. Though still within its testing phases, its armor proved strong enough to resist direct hits from Gundam's vulcan gun. While their Doms could dominate over other Mobile Suits, its abilities were still no match for Gundam. All three prototypes were wiped out at Odessa.
